constant death wobble 1500mi from home

3" black diamond pos shocks and 3" ome hd springs

I used to get horrible vibes when lightly braking because my rotors were warped. Now it happens every bump over 55. I need to slam on brakes down to 35 to fix. Not fun with semis on your *** on the highway. Anyway, its gotten progressively worse over the 1500mi trip I just took and will need to return 1500mi on sun. I thought it was my rear adco sway bar loosened. Which it was, so I tightened it. Still shakes horribly. Took it to my folks' mechanic, said a shock was loose. Sounded plausible. Until it just happened twice more on the highway.

Where should I start?? I need this thing to survive 1500 mi without the benefit of a saturdau mechanic.

Sorry if that's tough to read. On road, typed from blackberry.

Thanks in advance. I'm getting desperate.

rotors arnt going to be an issue, you arnt applying the brakes all the time so that wouldnt cause a vibration unless one or two of your calipers is dragging slightly which could be be unlikely, jack it up and spin the tires and see of the tread has a even straight line on it, look for any bubbles on the tires, maybe even balance the tires

No I haven't replaced the rotors yet. Nor is that my main concern right now. It happens literally every bump over 55mph. For those of you who haven't had the pleasure of driving on chicago expressways, there are bumps every 15'. I just had to slam on brakes to stop the wobble on the kennedy.

It seems to start in the back and move up my steering column. I've actually gotten it to stop before it became unrecoverable by slightly reducing speed. Once it starts the violent shaking the only thing I can do is slam on the brakes. I need this thing to at least make it back to my parents' tomorrow (65mi) and then can look for loose bolts etc. Maybe the winch I'll have in the trunk will help weigh the back down. It really feels like the crappy black diamond shocks work better under weight.

1500mi with constant death wobble is going to take years off my life. I just hope after this wkd I have years left!!

front track bar bushings, control arm bushings, steering components(tie rods, drag link), something is worn out or loose.

x2, start with the track bar bushings (have someone turn the steering wheel back and forth while you look at the track bar bushings for movement). And then go down the list. Good luck.

It was unbearable today and happening literally every bump. I am leaving at 7am tomorrow so I broke down (not literally) and took it to Midas (something I've never thought I'd do...but on Saturday at 1pm I was desperate). I asked them to replace the awful awful awful black diamond shocks and the steering stabilizer since I noticed a ton of play in the wheel.

They said the track bar bushings are showing signs of wear but not terrible.

I took it out, and while it seems like the bumps are better and the steering is tighter, right when I braked from 65, it happened again. Back to the rotors and bushings I guess.

I'm about at the end of my patience and am pretty much stuck. I can risk it and go, assuming I won't be braking a lot on the highway. But I think I just paid $469 for a band-aid....and not a very good one. If the wobble happens a lot on the drive, not only will it be slow and stressful, but I'm sure it'll kill this stabilizer as well.

Ironically the for sale sign is going on it right when i get back. This was supposed to be its last road trip. This thing literally needs to just make it 1500 more highway miles....just unfortunately all in one fell swoop. The midas folks said everything was tight. I hate this question, but what is the worst that can happen? I don't think the wheels are going to fly off. I just think I'll be uptight and nervous for 24hrs....

Midas said the TB bushings are showing wear, maybe there's enough wear for death wobble. DW is usually caused by the track bar bushings or bolt coming loose but that's just from all the reading I do on here, not from personal experience.

Ok...so it's dark and late. Quadratec says replacing the tbar bushings takes less than an hour. A search tells me a lot can go wrong (they seem like their a b*tch to remove). With just basic tools (I'm at parents house), is this something I can do tonight without jacking up the Jeep? Does anyone have a link to directions or a picture?

Thanks...

as with every other part I've tried getting from Advance today...they have no bushings. Actually said they don't even see a track bar on the '99 model.

Are there any other track bar bushings that would work? Ford, Chevy etc? This is getting ridiculous....

What about a complete track bar from a wrecker. It would be really easy to install as well.

you might be out of luck then. But at least get under there and make sure the tb bolts are tight...very tight. I have to tighten mine up about every 3 months or so. I get them as tight as I can.

What area are you in now maybe someone lives along the way and could help you if it becomes undrivable. I just replaced the tie rod end of my adjustable trackbar tonight, Ive had a month of slight death wobble.
